Cage workers carry out a wide range of financial transactions and handle any paperwork that may be required. They perform credit checks and verify credit references for people who want to open a house credit account. They cash checks according to rules established by the casino. Cage workers sell gambling chips, tokens, or tickets to patrons or to other workers for resale to patrons and exchange chips and tokens for cash. They may use cash registers, adding machines, or computers to calculate and record transactions. At the end of their shift, cage cashiers must balance the books.

Because the industry is scrutinized closely, cage workers must follow a number of rules and regulations related to their handling of money. Large cash transactions, for example, must be reported to the Internal Revenue Service. Also, in determining when to extend credit or cash a check, cage workers must follow highly detailed procedures.
